Department of Energy Makes Nearly $350 Million Available for Long-Duration Energy Storage

The U.S. Department of Energy (DOE) recently announced nearly $350 million for emerging Long-Duration Energy Storage (LDES) demonstration projects.

The LDES Demonstrations Program will be managed by DOE’s Office of Clean Energy Demonstrations (OCED) and will fund nearly $350 million for up to 11 demonstration projects -- projects that will contribute to the Department-wide goal of reducing the cost of grid-scale energy storage by 90% within the decade. DOE will fund up to 50% of the cost of each project.

The program aims to fund projects that will overcome the technical and institutional barriers that exist for full-scale deployment of LDES systems by focusing on a range of different technology types for a diverse set of regions.  

Letters of Intent are due by December 15, 2022, and full applications are due by March 3, 2023. Additional funding opportunities may follow this announcement to validate and accelerate commercialization of LDES technologies.  

In October, DOE issued a $30 million Lab Call Announcement for Long-Duration Energy Storage Demonstrations. Remaining funding for LDES programs will be covered at a later date.
